PulseAudio 100% cpu usage under KDE

Thu Jun 30 21:05:38 PDT 2016

So I have disabled pulseaudio, which worked fine. And I have installed the
gtmixer which at least gives me a gui for gnome3, that also works well.

I tried various apps and they all have sound .... so not missing pulse at
all ;)
By the way, I know I have asked this before, but what is the sound system
used by Dfly?
.. and how do I get an application to start at boot (like gtmixer), I don't
see the usual gui in gnome ..

Thanks,
Bernie
